"I think there are two sides of it, the investment side and the digital currency side,"

What a moron. Either its an investment or its a currency. A currency can't be a highly volatile asset. No one would accept it. Who'd sell a computer on ebay for $1000 to find that by the time they got the money it was only worth $700?

Either its volatile and an investment risk, or its a stable currency. It cannot be both.

Currency traders need to work with millions of dollars to make any potential profit worth the effort.

That's inconsistent with reality. Local currency exchange points are very common in Poland (because of how much the Polish enjoy job tourism, mostly). They need to freeze a few dozen thousand dollars to get things going, but it's a fairly safe business after that.

True, but what they're trading on is not the fluctuations of a currency but a market need for customers to exchange one currency for another. You probably need a fairly stable currency to do this.
